Data Eraser - iShredder

iShredder™ – data eraser and file shredder for Android
Keep control of private photos, documents and work files. iShredder by Protectstar lets you securely delete selected content and overwrite unused storage to help reduce traces of earlier files. Use it when clearing sensitive downloads, preparing a phone for repair or getting ready to sell, exchange or pass it on to a family member.

SECURE FILE DELETION, YOUR CHOICE
Select photos, videos, PDFs, downloads and folders with the built-in file explorer. Remove the files you no longer need without choosing to reset the whole phone. File access depends on your Android version, permissions and device. Supported storage options can include internal storage and compatible SD cards.

ALREADY DELETED THE FILES?
An unused-space wipe writes temporary data into available storage and removes it after completion. It is designed to reduce accessible remnants of previously deleted files. Unlike a storage cleaner, an unused-space wipe focuses on privacy. It does not create extra storage.

SELECT AN ERASURE METHOD
Available methods include single-pass and multi-pass overwriting, with options such as DoD 5220.22-M depending on your edition. Choose a method for the storage and task involved. Review the selected targets before starting. The amount of storage and number of passes affect processing time.

ASSESSED APP SECURITY
iShredder Android has undergone DEKRA MASA L1 app-security assessment based on selected OWASP MASVS requirements. iShredder also received the Fortress Cybersecurity Award 2025. The assessment concerns Android app security, while the award recognises iShredder as a cybersecurity product.

REPORTS AND ADVANCED FEATURES
Supported editions offer erasure reports for recording completed operations. They can help with device handover records, work checklists and internal documentation. Additional methods and reporting options depend on the edition. Keep the records you need when returning work equipment or handing over a device. Reports document the selected process.

FOR PERSONAL AND WORK FILES
• Delete private photos, scanned identity documents and sensitive downloads.
• Remove selected files before a phone exchange, repair or family handover.
• Process unused storage after deleting confidential content when needed.
• Clear accessible work files in line with your employer's device policy.
• Record supported erasure operations when preparing a shared device.

THREE STEPS TO GET STARTED
1. Back up what you need to keep and select the content or unused storage.
2. Choose an available method and review the scope before confirming.
3. Run the operation, check the result and save a report if your edition includes it.

UNDERSTAND THE UPGRADE
Some functions require an in-app purchase or subscription. Compare the features included in each offer and check its duration and renewal terms before purchasing. Select additional methods or reports for the tasks you expect to repeat, such as handling sensitive documents or preparing shared devices.

BEFORE YOUR PHONE CHANGES HANDS
Local erasure does not remove cloud backups or copies held on another device. Review them separately. For a full handover, also follow the phone manufacturer's account-removal and factory-reset instructions. iShredder works within Android's permissions; it does not provide unrestricted access to other apps' private data or protected work profiles.

PRIVACY AND DEVICE SUPPORT
Results depend on encryption, flash storage and Android access. App-level overwriting cannot guarantee erasure of every physical memory cell. Google Play's current Data Safety declaration states that data is encrypted in transit and not shared with third parties. Check the declaration and privacy policy for collection details.
